There is another legend about the formation of the dam. One day, Guanyin Bodhisattva had a dream for Liu Ji, the founding prime minister of the Ming Dynasty, and told him the mystery of dike building. Liu Ji woke up from his dream and ordered thousands of civilian boats from the state capital to go around the lake, carrying rice husks and stopping on the lake for standby. Two days later, the west wind blew on the lake. Under the command of Liu Ji, the lined-up civilian boats scattered rice husks and floated with the wind, reaching Jiangba in the south and Huaiyin Wharf in the north. The east bank of the lake gradually merged into a continuous wave line of rice husks. Liu Ji took a boat tour, which happened to have 108 big bend and small bend. He then ordered the drawing and bending according to the drawing, and the levee was strong and safe from now on. In the Qing Dynasty, Jin Fu continued the practice of the Ming Dynasty and continued to build levees until they were completed.

In fact, Liu Ji's dike building is just a beautiful legend, but it confirms the truth that "a spent force cannot cross the road". In fact, the same is true of water control. Traces left by rice husk indicate the strength of water potential. The real reason for the formation of the 108 bend is not from the dream of Guanyin, but because the levee has burst many times, and the breach is tens of meters deep. When repairing the dike, avoid deep and shallow, and move forward or backward 50 or 60 feet along the breach to form a crescent shape. Many crevasses have become the shape of today, which is also a scientific way to buffer lake waves. From 1580 to 17 1 year, more than 600,000 cubic meters of stones were used up. The Hongze Lake levee finally tamed the rolling huge flow from Changhuai River, allowing it to discharge flood and reduce pollution according to people's wishes, and enter the river and the sea. Nowadays, Hongze Lake levee has been protected as a key water conservancy project for thousands of years, and the trees on both sides of the levee are lush and have become natural oxygen bars. There are not only beautiful natural scenery here, but also many historical sites such as Hongze Lake Monument, Xinba Site, Qiao Zhou Datang, Jiulong Bay and Zhenshui Tieniu. At the southernmost tip of Hongze Lake levee, China designed the second largest sluice in China-Sanhe Sluice. This national water conservancy scenic spot is home to nearly 20 species of national first-and second-class protected birds, such as egrets, bustards and grey herons. Thousands of egrets and grey herons come here to live and breed in spring.
